Ncej qhov chaw yog rotating qhov chaw, nws qhov ntev yog ntau dua li txoj kab uas hla. Lawv feem ntau yog tsim los ntawm cylindrical nto, conical nto, puab qhov, threads thiab coj kawg lub ntsej muag ntawm concentric shafts. Raws li cov qauv sib txawv, cov ncej tuaj yeem muab faib ua optical axis, stepped axis, hollow axis thiab crankshaft.
1, Tsis muaj kev xaiv ntawm cov ncej
Raws li kev siv cov kev xav tau, hom ntau lawm, cov khoom siv thiab cov qauv, lub tes tsho lub tes tsho tuaj yeem xaiv cov ntaub ntawv dawb xws li tuav thiab forgings. Rau cov ncej nrog me ntsis txawv nyob rau hauv txoj kab uas hla ntawm lub voj voog sab nrauv, nws yog feem ntau dominated los ntawm tuav; Forgings feem ntau yog siv rau cov kauj ruam los yog cov ncej tseem ceeb nrog loj sab nraud qhov sib txawv, uas tsis tsuas yog txuag cov ntaub ntawv, txo cov haujlwm ntawm machining, tab sis kuj txhim kho cov khoom siv kho tshuab.
Raws li qhov sib txawv ntau lawm, muaj ob txoj kev forging ntawm dawb paug: dawb forging thiab tuag forging. Dawb forging feem ntau yog siv nyob rau hauv me me thiab nruab nrab batch ntau lawm, thiab tuag forging yog siv nyob rau hauv loj ntau lawm.
2, Cov khoom siv tsom xam ntawm cov ncej tes tsho
Cov khoom siv dawb yog 20cr380 * 55mm, thiab cov khoom ua haujlwm ntev. Nws yog ib qho nyuaj rau kev ua cov ncej slender. Nws yog ib qho tsim nyog los xaiv cov cuab yeej siv tshuab tsim nyog thiab txais yuav cov txheej txheem ua tiav, thiab xaiv qhov tsim nyog txiav thiab cov khoom siv kom tau txais qhov roughness Ra0.4.
Cov khoom xaiv rau kev txiav yog 20Cr, uas tuaj yeem txhim kho cov qauv thiab txiav kev ua haujlwm tom qab normalizing; Tshem tawm kev ntxhov siab sab hauv.
Normalizing lub workpiece tom qab forging tuaj yeem tshem tawm cov kev ntxhov siab sab hauv tsim thaum lub sij hawm forging, refine cov nplej, txo cov hardness thiab txhim kho kev ua tau zoo.
Txij li feem ntau ntawm cov nyiaj tau txais raug tshem tawm tom qab kev ua haujlwm ntxhib, txoj kab uas hla ntawm lub workpiece raug txo thiab nws yooj yim rau harden. Tom qab kub kub tempering, tempered sorbite qauv nrog zoo toughness thiab tej yam kuj yuav muab tau nyob rau hauv nruab nrab txheej. quenching thiab tempering kev kho mob tuaj yeem tshem tawm ib feem ntawm cov kev ntxhov siab sab hauv los ntawm kev ua haujlwm ntxhib, tsis yog kev kho kev laus, thiab deformation ntawm lub workpiece tom qab quenching thiab tempering yuav raug tshem tawm hauv cov txheej txheem tom ntej. Tom qab ua tiav txoj siav, high-frequency quenching yog nqa tawm los txhim kho lub zog, hardness thiab hnav tsis kam ntawm spindle. Quenching deformation tuaj yeem raug tshem tawm los ntawm kev sib tsoo hauv cov txheej txheem tom ntej, yog li kev xaiv cov khoom siv thiab kev kho cua sov ntawm qhov no yog qhov tsim nyog.
